**Torus Surface Area Calculator:** This torus surface area calculator will help you calculate a torus surface area for a given set of radii. You must have seen this shape on your plate as a doughnut or a bagel, or on the road beneath vehicles in your daily life. Read the further modules to learn what is meant by Torus Surface Area, its Formula, Procedure on How to use the Torus Surface Area Calculator along with Solved Examples on finding Torus Surface Area.

A torus is a three-dimensional form made by rotating a tiny circle with radius r in space around an axis that is parallel to a larger circle of radius R. To compute the surface area of a torus, use the following formula:

Surface area of Torus = (2πR)(2πr)

Surface area of Torus **= 4 π ^{2}Rr**

The radius of the cross-section r and the radius of rotation R, which is the distance between the centre axis and the centre of cross-section are the two radii that make up a torus.

Ring type (R > r)

Horn type (R = r)

Spindle type (R less than r)

The volume of Torus is given by:

**Volume = 2π ^{2}Rr^{2}**

There are steps to find the torus surface area using a calculator:

- Enter the outer radius or big radius value (R)
- Put the inner radius or small radius value (r)
- Press the calculate button to get the torus surface area will be appear on the screen.

**Question 1:** What does your average speed if the distance cover 4000 metres in 10 minutes?

**Solution:**

Consider the problem and the inputs are as such

The outer radius is 20 units

Inner radius is 10 units

The formula for finding the torus surface area is **Surface area = 4 π ^{2}Rr**

Surface area = 4 (3.14)^{2}*20*10

Surface area = 7887.68

Therefore, The surface area of a torus is **7887.68 sq.unit.**

**1. What is the formula for calculating the surface area of a torus?**

The surface area of a torus is calculated by multiplying the cross-section circumference by the ring circumference. The formula for the surface area of a torus is **4π ^{2}rR**

**2. Is a torus considered a surface?**

A torus is a revolving surface created by rotating a circle in three-dimensional space around an axis that is coplanar with the circle.

**3. What exactly is a torus?**

A torus is a three-dimensional circular shape with a cross-section of a circle. Doughnuts, tyres, and basketball hoops all have this shape. When you revolve a circle along a circular path along an axis normal to the circle, you get this shape.
